UGAB soft PU encapsulation adhesive
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Product specification 一、Product features: ? ? UGAB is a two-component resin system, forming a crystal clear after curing, glittering flexible high transparent solid. ? ? UGAB process of polyurethane resin synthesis, the production of products with excellent resistance to low temperature performance and high temperature resistant performance. ? ? UGAB products can be widely used in packaging with LED?strip?light and printed circuit board. 二、Conventional performance: Test item ?Test method or condition ?A ?B Appearance ?Visual ?Colorless to light yellow transparent liquid ?Colorless to light yellow transparent liquid Viscosity ?35℃ mpa·s ?600±200 ?1500±200 ?AB mixture viscosity ?900±200 Density ?25℃ g/cm3 ?1.02±0.05 ?1.04±0.05 Mixture ratio ?Weight ratio ?A :B = ?1 :1 Available time ?100g / 25℃ ?20 Minute Curing time ?Room temperature ?Room temperature 24 ~ 48 hours ?Heating curing ?After 3 hours of normal temperature, bake in the oven at 60 degrees for 3 hours。 Retention period ?25 degrees, seal ?Two months ?Two months 三、Colloid physical property: Test item ?Test methods or conditions ?A ?B Form ?—— ?Resin / polyol composition ?Curing agent / isocyanate prepolymer Colloid density ? ?1.03±0.05 Elongation ?% ?>50 Use temperature ?—— ?-30℃~110℃ Hardness ?SHORE A ?65±5 Yellowing resistance ? ?Outdoor use > 3 years; indoor use > 4 years 四、Use process: 1、Glue storage note: The suitable storage temperature of the glue is: 20 ~35 C / C, when the temperature is high, the polyurethane will self - polymerization, so that the glue becomes thicker Suitable for: glue storage humidity is less than 70%, high humidity, moisture will be a lot of adhesion on the surface of the bottom plate, and the moisture and so on adhesive properties of polyurethane reaction product, piebald, have adverse effects of bubbles. |
