 Chemline 7850 – Unique Flexible Polyurethane Resin Replicates Tree Bark & More

ST. LOUIS, MO – December 4, 2017 – Chemline, Inc. is a leading provider of polyurethane and polyurea coatings and elastomers. CHEMLINE 7850 is used by fabricators around the world to replicate the texture and appearance of real tree bark and other highly textured surfaces. With this molding process, you can quickly create large sheets of artificial bark, brick work or rock wall that can be pieced together to produce whole artificial tree trunks and branches or complete sheets of flexible brick and rock wall.

CHEMLINE 7850 is a two component, fast-set, spray-in-mold polyurethane that is 100% solids and zero V.O.C.  After spraying into a detailed mold, the cured sheets of CHEMLINE 7850 can be demolded quickly and then faux finished or stained. We have engineered this product to have exceptional tear and flexibility. It offers a great balance of Shore Hardness and enough elongation that allow for ease of wrapping around shapes and to follow the contours of variable backing/mounting surfaces. This product is easy to color or stain, meets the ASTME-84 Class 1 standard and has also passed ULC/CANS102 fire test.

CHEMLINE 7850 can be used in exterior or interior applications like amusement parks, zoos, museums, casinos and point of purchase displays.

Physical properties of CHEMLINE 7850 include:

Hardness…………………..Shore 95 A

Tear Strength………………240 pli

Application of CHEMLINE 7850 is very easy with a 1:1 high pressure, heated plural component proportioning unit and an impingement style spray gun. Recommended spray equipment is the Graco Reactor E-XP2 or H-XP2. Chemline, Inc. is also a GRACO HPCF Top 20 Advanced Distributor and can provide training on the use of the liquid materials as well as the proportioning equipment and spray guns.
