RTV-2

Liquid silica gel series

RTV-2 room temperature vulcanized silicone rubber

Model:? Fingerprint glue a

Uses: It is widely used for punching fingerprints of punch cards, collecting fingerprints of driving school exams, making injection molds of PU resin, unsaturated resin, polyurethane resin, wedding candles, gypsum handicrafts, soap handmade soap, tire turnover, etc.

Features:

★ Two-component silica gel: liquid silica gel and curing agent

★ Good fluidity, easy foaming and dumping.

★ High temperature resistance, acid and alkali resistance and low shrinkage.

★ High tensile strength, high tear resistance and more mold turnover times.

Addition ratio and reaction of curing agent:

1, adding 3-5% curing agent, operating for 30 minutes (room temperature), and completely curing the mold in 4-8 hours.

2. The mixing ratio of silica gel and curing agent is 100:3-5. For example, 100g silica gel, and 3-5g curing agent. The curing agent is provided free of charge at the rate of 5%. If users need shorter or longer operation time, in principle, do not add less or more curing agent, and should contact our company to provide newly prepared curing agent.

Users need to know:?

RTV-2 mold silicone is also called two-component room temperature vulcanized silicone rubber; It has good fluidity and operability. When 3%-5% curing agent is added, the silica gel can still flow within 30 minutes, and it takes 4-8 hours for the mold to completely cure. General mold can be used after 24 hours. At this time, the performance of the mold is relatively stable and the use effect will be better. The finished mold has the properties of acid and alkali resistance, aging resistance, difficult deformation and shrinkage, high temperature resistance and good tear resistance, and is widely used in fine mold reproduction, resin, Polly, gypsum, candles, handmade soap and other mold making.
