Water-white initial color
Kristalex™ 5140SD hydrocarbon resin is a high softening point, low molecular weight resin with low organic volatile content and low odor that complies with many FDA regulations for applications involving food contact. It is designed primarily for use as a modifier resin in high performance adhesives, coatings, and heat seal compositions. In these applications, its water-white color, heat stability, and resistance to oxidation and discoloration are the advantages. Compliance with a given regulation in a specific situation should be verified prior to use in a food contacting application. In EVA-based hot melt adhesives, Kristalex 5140SD has useful compatibility with EVA grades with 20%-40% vinyl acetate and is useful in formulating low-color adhesives with improved high temperature resistance. In styrenic block copolymer based adhesives, Kristalex 5140SD preferentially associates with the styrenic endblocks, producing higher cohesion at temperatures up to 70°C without affecting tack and adhesion properties.

Compatibility and Solubility
Compatible in useful proportions with chlorinated paraffins, polystyrene, rosin and modified rosins, rosin ester, styrene-butadiene rubber (SBR) and SBR block copolymers, polyvinylchloride (PVC), acrylonitrile-butadiene-styrene (ABS), as well as modifying the styrenic endblocks of all styrene-containing block copolymers. Soluble in aromatic and chlorinated hydrocarbons, esters, and ketones. Insoluble in aliphatic hydrocarbons; alcohols and glycols. Limited solubility in nitroparaffins. For low or zero VOC systems, Kristalex™ 5140SD is soluble in the VOC exempt solvents acetone, methyl acetate, 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.
Pastilles in multi-wall paper bags (50 lbs, 22.7 kg net wt).
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.
