Water-based adhesives to polymer polymers, water-soluble resins and other raw materials, water as a solvent, small odor, environmental protection. With the continuous improvement of people's awareness of environmental protection, in recent years, water-based adhesives began to become the mainstream of the market.
water-based adhesive characteristics
1, applicable substrates any kind of adhesive is not lm-
.
present, water-based adhesives are mainly used for the bonding between polished paper/paper, PET/paper, BOPP/paper, PVC/paper, plastic/plastic and other substrates.
2, inherent
every water-like adhesive has its "inherent characteristics".
characteristics of water-based adhesives mainly include appearance (product appearance and film appearance), solid content, density, pH, solvent ratio, opening hours, resistance to high/low temperature, initial viscosity, curing viscosity and so on.
water-based adhesive bonding methods are generally divided into machine, hand, machine and hand stick and use three, different bonding methods correspond to different inherent characteristics.
, for example, when the use of machine adhesive, the requirement of water-based adhesive opening time is short, when the use of hand adhesive, the requirement of water-based adhesive opening time is long.
In terms of high/low temperature resistance, water-resistant adhesive is required to bake within a safe range for 72 hours, and then after 72 hours of freezing, the bonding strength remains unchanged, no degeling, film brittle and other phenomena.
sealing glue attention to the use of
1, water-like sealing glue operating temperature, to be more than 0 degrees of construction or ice damage adhesive performance can not even be used;
2, beware of splashing into the eye, if accidentally entered immediately with water flushing treatment;
3, in the process of use do not self-water debugging;
4, do not pour waste liquid directly into the
sewer or river, the remaining residual static drying film after solid waste treatment
