KhimGermet A (1K) acrylic joint sealant — water-based

Joint sealants

Its water base makes KhimGermet A (1K) easy to work with: the sealant tolerates a damp substrate without droplets, and tools are cleaned with water. It is used to seal joints, gaps, seams and cracks in vertical and inclined structures made of concrete, foam concrete, brick, plaster, metal, PVC and wood, and in horizontal ones — without direct mechanical load; it is not intended for expansion joints of panel buildings. Elongation at break is at least 300%, and a surface skin forms in no more than 30 min.

Specifications

ManufacturerKhimtrast — AO “Khimtrast”, Nizhnekamsk
Typejoint sealants
Usejoints and abutments
Baseone-component water-based sealant: a suspension of fillers, thickeners and plasticisers in an aqueous dispersion of a synthetic polymer with stabilisers; cures by drying in air; density at 23 °C 1.63–1.67 g/cm³
Colourwhite or grey
Packagingplastic bucket 10 l – 10 kg
Application methodsealing of joints, gaps, seams (except expansion joints of the envelope structures of panel buildings) and cracks in vertical and inclined structures made of concrete, foam concrete, brick, plaster, metal, PVC, wood, and in horizontal ones — without direct mechanical load; after transport at −30…0 °C keep for 24 h at +5…+25 °C; clean off dust, cement film and old sealant with wire brushes, blow out, degrease with xylene, toluene or acetone, moisten in hot weather; a damp substrate without droplets is permitted; press into the joint 1–5 mm deep and 10–50 mm wide with a spatula without voids, immediately level and compact; for depths over 5 mm — in layers after the previous one has dried; wash tools with water
Application temperatureair +5…+35 °C; humidity max 80%; substrate 3 °C above the dew point
Curingsurface skin max 30 min at (23±2) °C and humidity (60±10)%; drying slows down as the temperature drops
Key propertiesrelative elongation at break at least 300%; nominal tensile strength at least 0.15 MPa; adhesion at least: concrete 1.0 MPa, wood 1.0 MPa, steel 0.8 MPa, glass 0.8 MPa, PVC 0.4 MPa; flow in vertical joints max 2 mm; predicted service life at a thickness of 3 mm at least 10 years; service temperature from −40 to +80 °C
Layer thicknessjoint 1–5 mm deep, 10–50 mm wide
Shelf life12 months from the date of production; storage and transport at −30…+35 °C in closed original packaging
StandardsTU 20.30.22-097-27903090-2022; certificate of conformity No. 0022203 (certification body Tvereks, RA.RU.11AM05), 30.08.2022–29.08.2025
