Special resin

Saturated polyester resin BH-14

Type ：High molecular weight linear saturated polyester with very good adhesion to metals.

Application: The baking coating made of BH-14, amino resin and blocked polyisocyanate has excellent flexibility and strong adhesion to metal. Coil coating primer and bottom surface in one coating, composite adhesive; deep-drawing and sterilization-resistant printing iron coatings, metal decoration and inner protection coatings; gravure and rubber letterpress inks and heat-sealing coatings.

Supply form: granular solid resin

(1) Measure 0.5 grams of polyester in a mixed deep solution of 100 cm3 of phenol and dichlorobenzene (50/50.w/w)
(2) Differential thermal analysis

Storage stability:

BH-14 can be stored for at least 12 months at room temperature below 25°C under the condition of avoiding direct sunlight and moisture, BH-14 will produce turbidity in solution (a very small amount of cyclic oligomers) ).

Packaging: Granules packed in paper bags, net weight 25kg.
