Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives

for Standardization - Part 1.Rules for the Structure and Drafting of Standardizing Documents.

This document serves as a replacement for JC/T 864-2008 Polymer Emulsion Architectural

Waterproof Coating. In comparison with JC/T 864-2008, apart from structural adjustments and

editorial modifications, the main technical changes are as follows.

a) The scope of the Standard is modified (see Chapter 1; Chapter 1 of Version 2008);

b) The product classification is modified (see 4.1; 3.1 of Version 2008);

c) The technical indicators of appearance are modified (see 5.1; 4.1 of Version 2008);

d) The low-temperature flexibility item is deleted; the inspection items, technical

indicators and test methods for "density, low-temperature elongation at break, tear

strength, low-temperature bending properties (standard state, heat treatment, alkali

treatment, acid treatment, artificial weathering aging), water resistance, bond strength

(standard state, damp substrate), flammability, water absorption (optional), and limits

for hazardous substances" are added; the test methods for tensile properties (standard

state, heat treatment, alkali treatment, acid treatment, artificial weathering aging) are

modified; the time for heat treatment and artificial weathering aging is extended (see

5.2, 6.6, 6.10 ~ 6.12, 6.14, 6.16, 6.22 ~ 6.30; 4.2 and 5.4 of Version 2008);

e) The specimen preparation method is adjusted, and the coating thickness is modified

from "1.2 mm ~ 1.5 mm" into "(1.5 ± 0.2) mm" (see 6.3; 5.4.2 of Version 2008);

f) The judgment rules are modified (see 7.4; 6.3 of Version 2008);

g) The marking, packaging, transportation and storage requirements are modified (see

Chapter 8; Chapter 7 of Version 2008).

This document does not contain any terms or definitions that require clarification.

4 Classification and Labelling

4.1 Classification

4.1.1 Products are classified into general-purpose (T) and high-elasticity (G) types in

accordance with application requirements.

NOTE 1.the main raw materials for general-purpose products are generally emulsions (such as

pure acrylic emulsion and styrene-butadiene emulsion) synthesized using traditional

emulsion polymerization methods.

NOTE 2.the main raw materials for high-elasticity products are generally emulsions (such as

aqueous polyurethane emulsion) synthesized using non-traditional emulsion

polymerization methods.

4.1.2 Products are classified into exposed (E) and non-exposed (N) types in accordance with

whether they can be used in the open.

4.2 Labeling

Products are labeled in the order of product name, document No., product type, and whether

they can be used in the open.

EXAMPLE. high-elasticity polymer emulsion architectural waterproof coating conforming to this

document are labeled as.
