Does cutting the glass using this system create any tensions along the cut surface of the glass .I am thinking to make holes of diameter 24 cm inside glass slabs of dimension 30 x 30 cm using the water jet.The only doubt is whether the cutting process can result in some tension which need to be...
A problem which we are presently facing is that orthophthalic polyster resin purchased from two different locations are having two different colours .One is yellowish whereas the other tends towards green . Due to the big difference in the colour the products made from these two locations though...
I am reading more and more these days on powder coatings .The doubt which I have is whether application in the traditional manner ie,spraying the coating over the substrate in a liquid form is inferior in terms of physical and chemical properties with respect to a coating applied using the...
Do the colouring pigments used within a thermosetting resin have an effect on the curing temperature or on the quality of polymerisation which occurs .
I have observed that some colours like red when present in the resin cause the polymerisation to occur to a lesser degree than in a resin which...
Can someone please clarify to me whether there is a relationship between Tg( the glass transformation temperature of the resin) and the the curing temperature of the resin ?Are they the same .Is it possible that a thermosetting resin has a Tg of 50 degC and which cures at 130 degC ?
Best...
I would like to know whether non-yellowing polyurethanic resins are available in the market . In case they do ,please point me to some sources or links .
Thank you in advance .
I am presently sticking glass( of 4 mm thickness ) using polyester resin onto fibre glass of around 2mm thickness . However the problem I have is that many of the pieces seem to break after some days .
My feeling is that there is an incompatibility in the coeffecient of expansions of the two...

I dont know whether this question is appropriate on this forum or in the polymer forum and so I will post this also there .

I have doing some jobs by pressing glass into shapes . The major problem encountered in this case is the ripples which appear on the surface of the glass which is contact with the mould due to the glass cooling down as it spreads before the plunger presses it . Increasing the mould temperature...
