Some light reading (actaully, pretty technical!) about speed glue... LINK
I think I used to have another paper regarding speed glue and booster (by Waqidi Falicoff), but can't find it.
Note that modern boosters and old school (Like ASTI) boosters seem pretty different. The old ASTI booster was basically just the solvents from speed glue - without the rubber. That stuff was VERY strong, but didn't last any longer than speed glue. bes |

Well, even the Japanese people suspect Tenergy came boosted at the factory(noting its huge performance lead over the Tensor back when it was first released) and Mizutani used it without being aware.

Its known that sponsored players have a tiny metal bottle with booster. And mizutani was carrying that small bottle in a worlds there are boosters from nittaku donic butterfly. A korean women in the us open also had that metal bottle sold one to a coach |

Ok, so back to boosters and how they work - boosters expand the sponge, just like adding water to a dry sponge. And they thusly soften the sponge, increasing dwell time, and also stretch the topsheet, making it more spinny. Correct?
Is there a difference between different boosters, and if so - what is the nature of the difference. And what is booster? I've seen it referred to as a type of oil, is that what is is? And an unrelated question - I'm on my fourth coat of booster on two sheets of H3 Neo (to be used as forehand rubber on two different blades). The sheets are curled into tubes. The youtube videos I've seen say to wait until the sheets uncurl. In my experience, they never do. Should I just go ahead and glue them with enough glue to hold them to the blades? Or weigh them down under books or something, to uncurl them? |

The part about dwell time is not well understood, especially how it affects spin. It is a complex interaction involving multiple elements, namely friction and elasticity. The general rule follows that as the bounce increases, dwell time decreases, yet the ability to spin is closely dependent on it.

IMHO the best thing about booster is they give an amazing feeling, wich unfortunatelly doesn't last more than couple of weeks.

Better table tennis through chemistry? I suppose that would depend both on your perspective of the sport and to a lesser extent on how much table tennis you have played and how many changes tt has gone through since you first started playing it. |

Does anyone have any advice as to whether or not you need to wait until the boosted sheet has uncurled? The last time I boosted, I waited 4 days. The sheet was still very curled up, so I just gave up and glued it anyway. Do you people do that too? The youtube videos say to wait until it is uncurled. It seemed to work fine doing it my way, although the first time I tried to glue it, it curled partially off the next day. So I glued it again (and the second coat of glue expanded the rubber again quite a bit!)

Thanks. That's a great thread on the topic! Many of the pictures have bad links though. Is there any way you can fix?

If you dont want rubber to curl then dont let it curl in the first place!!!

Ok, I'm done with this batch of boosting - two sheets of H3 Neo Prov, 4 coats of Falco tempo booster. One sheet went on a Viscaria blade I use for playing, and the other on a blade I use with my Amicus robot. I'm redoing another sheet to put on my playing blade. I'm not too happy with how it came out - I think I put on too thick a coat of glue, and the topsheet came out kind of lumpy. Plus my son's friend just tried using the Viscaria, and dove for a ball and braced his fall with the blade and tore the topsheet a little on the side. Remind me not to let kids use the good equipment. Anyway, the robot blade has H3 Neo Prov on both sides, but only one side boosted. I thought I'd try to see if I could tell a difference. I programmed the robot to serve a fairly fast ball with moderate topspin, and held the blade in front of the balls in the same position, for both sheets of rubber. Frankly, I couldn't detect any consistent difference between the boosted and unboosted rubbers. Can anyone suggest a better way to do the experiment? Also - people sometimes refer to booster as oil. It's not oil, is it? (And just to be clear, I don't have any real expectation for this to make a big difference in my game. I'm not at the level where it would. I'm doing this mostly for fun - it's fun to play with this stuff. And I hope to learn a little bit about the characteristics of rubbers by doing these comparisons.)

Maybe a bad / too soon a glue job? IMHO, especially within a few days of boosting, one should be able to detect just by the sound: the boosted rubber should sound (upon hitting) like you just fired a gun, if boosted properly. |

Maybe. I did give it a couple of days between the last coat of booster and putting the sheets on. It could just be that the balls weren't being shot hard enough to penetrate the sponge.
Another thing - someone in that other thread pointed out that you need to remove the protective film from the topsheet before applying booster. Good point, and I hadn't done that. Otherwise the film prevents the topsheet from expanding when the sponge stretches. |

There should definitely be a consistent difference between boosted and unboosted rubber. I remember a few years ago before I improved significantly in play, I could tell the distinct difference between boosted and unboosted hurricane. You need to put it through varying 'load' in an actual game situation or in training to be able to notice it. You can't throw balls at it and leave the bat there and expect to feel any significant difference.
If boosted correctly and played correctly, not only should you hear the audible click clack difference but you should also be able to feel that the ball catapults more off the rubber and the rubber is faster by far. I've tried different sheets of Hurricane: unboosted commercial, unboosted blue, boosted blue, boosted provincial and unboosted neo. There is a fine line between boosted and unboosted. Unboosted is very lackluster to me. I can flick against just about any serve with H3 against a particular training partner that I tested the rubbers with but it is extremely slow in play. I've found with unboosted sheets you can get spin fine but you also have to put in a lot of effort into putting on speed. Unless you have a miraculous stroke with heaps of momentum, your shots will either be moderately paced with moderate spin or very fast but borderline flat... relatively. This is coming from a spin oriented player. I know the age old argument of you should do athletic drills and whatnot but when you're using your playstyle as a controlled variable and keeping it consistent with the independent variable of bat setup, there is a difference for sure. Quick question of my own: From my experience, majority of the young players are straying away from spin and are insistent on speed. Is this phenomenon happening around the world where everyone else plays? I'm not sure if it's a lack of training or just a shift in play style. I'm seeing a number of players in my club which has drastically reduced in size picking up fast rubbers such as tenergy or rasant but few of them play with heavy spin let alone much spin alone... I'll be testing my boosted rubbers as fatt has mentioned this Friday and I'll verify all this. I haven't played with boosted sheets in a while.
