Requirements:
1, suitable viscosity: easy to stick easily tear;
2, peel force stability: small changes over time, that is, the stripping force increases the smaller the better;
3, good weatherability: sunlight exposure conditions, the use of up to six months to a year;
4, long shelf life: stored in the warehouse for more than a year, no change in quality;
5, no pollution, no corrosion: the adhesive is inert, will not be sticky material surface chemical reaction;
6, excellent mechanical properties: in line with user requirements tensile strength, elastic modulus, elongation and so on.
