ASTM D6083-2021 Standard Specification para sa Liquid Acrylic Coatings para sa Roofing
abstract
This specification covers the testing and material properties of water-dispersed protective roof coatings composed of water-based acrylic latex elastic emulsion polymers, where a variety of pigments and other additives are added to provide the desired physical properties. The manufactured product shall be in liquid form and may be applied to the roof surface by brushing, scraping, rolling or spraying. Its application guide is not discussed here. The coating must be tested and meet the liquid characteristics required for solid viscosity, volume and weight. Conversely, the film should also conform to the physical properties of drying as follows: initial elongation at break; Initial tensile strength under maximum stress; The final elongation at break after accelerated weathering; Through; Edema; Adhesion force; Fungal resistance; Tear resistance; And low temperature flexibility after accelerated weathering.

1.1 This specification covers liquid application of water-dispersed acrylic latex elastic protective roofing coatings.
1.2 This specification does not provide guidance for application.
1.3 Values expressed in SI units or inch-pound units shall be treated separately as standard values. The values specified in each system may not be completely equivalent; Kaya nga, bawat sistema ay dapat gamitin nang malaya sa isa't isa. Combining values from two systems may result in nonconformity.
1.4 Ang pamantayang ito ay hindi nilayon upang tugunan ang lahat ng, kung meron man, mga alalahanin sa kaligtasan na nauugnay sa paggamit nito. Responsibilidad ng mga gumagamit ng pamantayang ito na magtatag ng angkop na kaligtasan, mga kasanayan sa kalusugan at kapaligiran at upang matukoy ang pagiging angkop ng mga paghihigpit sa regulasyon bago gamitin.
1.5 This international standard is based on the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Mga Patnubay at Rekomendasyon na inilabas ng WTO Committee on Technical Barriers to Trade.
