Abstract:
The invention relates to a dispersion or solution of a polymer in water, organic solvents or mixtures thereof. The invention is characterised in that the polymer contains at least 0.001 mols of 3,4 dihydroxyphenyl groups (calculated at 109 g/mol) for 100 g polymer.
Abstract:
A process for producing moldings, in which a solventborne or aqueous, pigmented coating composition (P) and a free-radically crosslinkable coating composition (K), which after crosslinking to completion produces a transparent coating (KE) are applied to a support sheet, a dried but as yet not completely crosslinked coating (KT) is produced from the coating composition (K), the coated support sheet is shaped and is injection backmolded or foam-backed with a liquid polymeric material, and the coating (KT)—if this has not already taken place—is cured or aftercured; the crosslinkable coating composition (K) comprising a free-radically crosslinkable component (KK) which comprises carbamate and/or biuret and/or allophanate and/or urea and/or amide groups.
Abstract:
The invention relates to radiation-curable, water-emulsifiable compounds containing isocyanate groups or capped isocyanate groups, and to their use.
Abstract:
A mixture of at least two compounds each having at least two double bonds, said mixture having a WFR from 200 to 600 g/mol of double bond and at least two of said compounds each comprising at least two (meth)acrylic esters as double bond component, WFR being given by: ∑ i = 1 n α i ⨯ MW i / Z i = WFR where ∑ i = 1 n α i = 1 αi is equal to the molar fraction of compound (i) in said mixture,n is equal to the number of compounds in said mixture and n is ≧2,Zi is equal to the number of double bonds in said compound (i),MWi is equal to the molecular weight of said compound (i).
Abstract:
The present invention relates to free-radically curable coating compositions, to methods of curing such coating compositions, and to their use.
Abstract:
A radiation-curable composite layered sheet or film comprising at least one substrate layer and one outer layer, said outer layer being composed of a radiation-curable composition having a glass transition temperature of more than 40° C.
Abstract:
The present invention relates to a radiation-curable coating composition comprising at least one aliphatic urethane (meth)acrylate which has two ethylenically unsaturated double bonds per molecule and contains at least one polytetrahydrofurandiol in built-in form and at least one monoethylenically unsaturated reactive diluent. The invention further provides a process for producing a coated substrate using such a radiation-curable coating composition and to the coated substrates obtained by this process.
Abstract:
The present invention relates to novel (meth)acrylic esters of polyalkoxylated trimethylolpropane of the formula where EO is O—CH2-CH2- PO is independently at each instance O—CH2-CH(CH3)- or O—CH(CH3)-CH2- n1, n2 and n3 are independently 4, 5 or 6, n1+n2+n3 is 14, 15 or 16, m1, m2 and m3 are independently 1, 2 or 3, m1+m2+m3 is 4, 5 or 6, R1, R2 and R3 are independently H or CH3, a simplified process for preparing these esters and the use of reaction mixtures thus obtainable.
