Identification method of silicone adhesive

There are many kinds of silicone sealant: silicone sealant, polyurethane sealant, polysulfide sealant, acrylic sealant, anaerobic sealant, epoxy sealant, butyl sealant, neoprene sealant, PVC sealant, and asphalt sealant. The identification of silicone adhesive mainly depends on the following properties:
1、 breaking strength (breaking force/cross-sectional area);
2、 Bonding strength (pulling force/bonding area, excluding substrate damage);
3、 Elongation at break (length at break/original length);
4、 Anti-aging capability;
5、 Appearance (sub light, particles, bubbles);
6、 Shape retention (no drawing, no sagging of the facade);
7、 Shelf life;
8、 Curing time.

There is no difference between good and bad. Performance corresponds to price. there is stability and adequacy, which is a test for manufacturers. If the capacity of the sealant is less than the marked capacity (note: it is the capacity. This situation is very serious for the sealant), such sealant . There is a problem with the business idea of such enterprises, and the product is not much better. (There are many problems, which prove that the product production process is not strictly controlled). If the amount is large, the production stability of sealant should be considered.
