Technical Data Sheet
Regalrez™ 1085 Hydrocarbon Resin
Case and carton closures
Labels non food contact
Paints & coatings
Excellent thermal and UV stability
Low softening point
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 contains no added antioxidants or UV stabilizers.

Compatibility and Solubility
Regalrez™ 1085 is compatible at all ratios or in limited but practically useful proportions with polyethylene, polypropylene, natural and synthetic rubbers, SBR, polychloroprene, EPDM, butyl rubber, ethylene-propylene copolymers, APAO (amorphous poly-alpha-olefins), OBC (olefinic block copolymers), mPE (metallocene-catalyzed polyethylene) copolymers, mPP (metallocene-catalyzed polypropylene) copolymers, and the isoprene, ethylene-propylene and ethylene-butylene midblock of SIS and SEPS, and SEBS block copolymers. Regalrez 1085 can be used with EVA copolymers with less than 32% vinyl acetate, EnBA (ethylene n-butyl acetate) copolymers, paraffin, microcrystalline and polyolefin waxes. Regalrez 1085 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 (TBA) and perchlorobenzenetetrafluoride (PCBTF) 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.

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. The useful life of this product can be affected by storage and handling conditions. When stored in the original unopened container in an enclosed area and protected from moisture, extreme temperatures and contamination, the shelf life of this product is estimated to continue to meet applicable sales specifications for 3 years from the date of manufacture. Shelf life is a guide not an absolute value. The product should be reanalyzed for critical properties at the end of its shelf life to see if it meets specification for use.
