Product Description
Regalrez™ 1085 hydrocarbon resin is produced by polymerization and hydrogenation of pure monomer hydrocarbon feedstocks. It is highly stable, light colored, low molecular weight, nonpolar resin suggested for use in adhesives, coatings, sealants, and caulks. Regalrez™ 1085 is especially suited to applications where the lowest color and most stability against weathering and thermal degradation is required. Regalrez™ 1085 is suggested for use in elastomeric sealants and adhesives tapes where outdoor exposure will occur or where clarity and resistance to yellowing is a requirement. Due to its relatively low softening point Regalrez™1085 is especially useful in formulating systems designed to perform at low service temperatures such as freezer labels or exterior-use sealants. Regalrez™ 1085 contians no added antioxidants of UV stabilizers.

Compatibility and Solubility
Regalrez™ 1085 is compatible with natural rubber, SBR, polychloroprene and the isoprene, and butadiene midblocks of SIS and SBS block copolymers as well as modifying the styrenic endblocks of all styrene-containing block copolymers. Regalrez™ 1085 can be used with EVA copolymers with up to 32% vinyl acetate. Regalrez™ 6108 is soluble in aliphatic and aromatic solvents, C5 and higher esters and ketones. It is insoluble in glycol ethers, glycol ether esters, and alcohols. For low/zero VOC systems Regalrez™ 1085 is soluble in t-butyl acetate and perchlorobenzenetetrafluoride (PBCTF) and will tolerate some acetone and/or methyl acetate as a diluent in solvent systems based on TBA and/or PCBTF. VOC exemptions and environmental regulations vary regionally and compliance with local standards should be verified before any claims about VOC content are made.

Packaging
Pastilles, in multi-wall paper bags (50 lbs, 22. 7 kg, net wt).

Storage

Due to the thermoplastic behavior, pastillated and flaked resins may fuse, block or lump. This can be accelerated under any of the following conditions: 1) above ambient temperature, 2) prolonged storage, 3) pressure, e.g., stacking pallets, or a combination of these conditions. This is particularly applicable for low softening point resin grades.

In order to maintain the flake or pastille shape, we therefore recommend storing the material in a temperature-controlled area, be careful with stacking material or applying pressure and preventing prolonged storage.

It should be noted that lumping does not have a negative impact on the product specifications. Due to the nature of the product, claims regarding lumping cannot be accepted.

Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on the solubility of the resin in organic solvents or on its compatibility with polymers. Accordingly, it is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.
