Kristalex™ 3105SD Hydrocarbon Resin is a water clear, highly color stable, nonpolar, low molecular weight thermoplastic polymer with low organic volatile content. This resin is compatible with a wide variety of oils, waxes, alkyds, plastics, and elastomers, and is soluble in many common organic solvents. It is indicated for use in plastics modification, adhesives, coatings, sealants, and caulks. In EVA-based hot melt adhesives Kristalex™ 3105SD is compatible with EVA grades with up to 18% vinyl acetate and is useful in formulating low-color, low odor adhesives with good low temperature properties. In styrenic block copolymer based adhesives Kristalex™ 3105SD preferentially associates with the styrenic endblocks, producing higher room-temperature cohesion without affecting tack and adhesion properties.Kristalex™ 3105SD complies with many FDA regulations for applications involving food contact. Users of this product should determine its compliance for their specific application prior to use.

Compatibility and Solubility

Compatible in useful proportions with a wide variety of materials, including styrene-butadiene rubber (SBR) and SBR block copolymers; neoprene, nitrile, polybutadiene, and acrylic polymers; chlorinated rubber; ethylene-vinyl acetate (EVA) resins; styrenated, vinylated, and drying oil alkyds; rosin ester resins; and ethyl-hydroxy-ethylcellulose (EHEC). Soluble in aliphatic, aromatic, and chlorinated hydrocarbons; esters; and ketones. Insoluble in alcohols and glycols; limited solubility in nitroparaffins. For low or zero VOC systems Kristalex™ 3105 is soluble in the VOC exempt solvents t-butyl acetate 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.

Storage & Handling

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.
