Sealing lacquer for application in a printing process
Sealing lacquer for application in a printing process, in particular for sealing packaging parts which can be peeled off from one another. The sealing lacquer has in particular a) 40 to 65 wt % solvent, b) 0 to 10 wt % styrene butadiene block copolymer, c) 8 to 12 wt % styrene alpha methylstyrene, d) 6 to 12 wt % linear and/or radial Tri-block (SBS) block, e) 0 to 10 wt % linear Di-Block (SB) block, f) 15 to 30 wt % polyester, and g) up to 3 wt % antioxidant. The sealing lacquer provides a seal that, whether the seal is opened by peeling, or the packaging is push-through packaging, provides a holding force exhibiting a strength until cohesion failure that is determined by the pressures and temperatures used during sealing.
Ultrahigh melt flow styrenic block copolymers
The disclosure relates to a hydrogenated styrenic block copolymer with high vinyl content, low viscosity, low order-disorder temperature and improved processability. The hydrogenated styrenic block copolymers can be extruded or molded with a minimum of additives. The hydrogenated styrenic block copolymers have high melt flows allowing for ease in processing such as injection molding, overmolding, dipping, extrusion, roto-molding, slush molding, fiber spinning, film making, 3D printing and foaming.
ANTIFOG COMPOSITIONS AND ARTICLES MADE THEREOF
The disclosure relates to an article comprising a substrate and an antifog coating layer provided on at least one surface of the substrate. The antifog coating layer comprises a sulfonated styrenic block copolymer (SSBC) having a block A, a block B, and a block D. Block A is a polymer block resistant to sulfonation and derived from a para-substituted styrene monomer, block B is a polymer block susceptible to sulfonation and derived from a vinyl aromatic monomer, and block D is a polymer block resistant to sulfonation and derived from a conjugated diene monomer. The antifog coating layer provides long-term antifog as well as anti-microbial protection properties. The selection of a specific solvent system can modify the SSBC film morphology leading to enhanced antifog property. The antifog coating layer adheres well to targeted substrates and has abrasion resistance property.
Shingle roofing coating method and composition
A method for generating a shingle roof coating is described. The method includes receiving an asphalt feedstock and separately proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the asphalt feedstock. The method then mixes the first concentrate with the asphalt feedstock and heats the combined first concentrate and the asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.
