Application No. 09/333,917
Further details of this appealed subject matter are recited in
representative claims 1, 3, 4, 7, 8, 10, 13, 17, and 18
reproduced below:
1. A low-odor, cold-curing (meth)acrylate
reaction resin for a floor coating, consisting of:
(A) (a) 50-100 wt% of a (meth)acrylate
consisting of
0-5 wt% of a methyl (meth)acrylate;
0-5 wt% of an ethyl (meth)acrylate;
0-97 wt% of a C3-C6 (meth)acrylate;
0-50 wt% of ≥C7 (meth)acrylate;
3-10 wt% of a multifunctional (meth)acrylate; and
(b) 0-50 wt% of a comonomer, consisting of
0-30 wt% of a vinyl aromatic; and
0-30 wt% of a vinyl ester
wherein the sum of all components of (a) and (b) in
(A) is 100 wt%;
(B) 0-2 parts by weight per 1 part by weight of
Component (A) of a pre-polymer that dissolves or
swells in (A); and wherein the proportion of methyl
(meth)acrylate or ethyl (meth)acrylate is less than 5
wt%, based on Component (B);
(C) 2-5 parts by weight per 100 parts by weight
based on Components (A) + (B) of at least one paraffin
and/or wax;
(D) a redox system, containing an accelerator
and a peroxide catalyst or initiator in an amount that
is adequate for cold-curing of Component (A); and
(E) optionally, at least one conventional
additive,
wherein the multifunctional (meth)acrylate and
component (C) are together present in an amount
effective for the reaction resin, when applied to
concrete at a thickness of approximately 1 cm and set
at ambient temperature for 90 minutes, to be non-
tacky.
3. The reaction resin according to Claim 1,
wherein Component (A) contains at least one
(meth)acrylate ester selected from the group
