Self - adhesive liquid silicone in the use of these points
20 Mar 2020
Self-adhesive small make up in the previous several articles have been repeatedly introduced, today mainly to friends to share the use of self-adhesive liquid silicone in the use of a few points to note, these must be remembered, conrebon suggests that you must remember in the use process.
Notes for viscous liquid silica gel:
: tools clean - the tools to take a b must be separated, or must be wiped clean before each use, to avoid mixing the two to cause local caking and lead to normal use;
: storage time -- it is recommended to store under the condition of 25℃, the safe storage period of A/B agent after full mixing is 0.5-3 days (curing speed is different), the higher the temperature, the shorter the storage time of self-adhesive liquid silica gel will be.
(3) storage environment: when in use, avoid contact with the rubber material containing N, S, P, Sn and other compounds, otherwise it will lead to unvulcanized vulcanization is not safe.
Clean the substrate -- because some mold oil or substrate transfer process did not deal with the substrate caused by pollution, so it is recommended that the best plastic material before the cover with alcohol or white electric oil wipe clean (can use white electric oil, lower costs), so as not to affect the adhesion of self adhesive special body silicone effect.
Pay attention to the release agent and additives -- it is best not to use the internal release agent or "white lubricant" of the thermoplastic substrate, and avoid the use of sulfur or amine additives, because they will inhibit the solidification of silica gel.
