quartz sand (or river sand). characteristics. fractional composition: at least 0.06–1.2 mm; origin: natural quartz or river sand; grain shape: angular, crushed or partially rounded; color: light yellow, white or gray; content of clay and dust particles no more than 1.0%; free of clay impurities in lumps and organic impurities; moisture upon delivery: no more than 5%; bulk density: at least 1300–1500 kg/m³; true density of grains: at least 2600–2650 kg/m³; hardness on the Mohs scale 7 (high resistance to abrasion); filtration coefficient: at least 5 m/day.
Two-component polyurethane adhesive for lawns and artificial grass. Characteristics. Composition: component A: polyurethane resin; component B: isocyanate hardener; does not contain water and organic solvents. Color of the mixture: beige / light brown; ratio of components: approximately 9:1 by weight; mixture viability at +20°C: no more than 30–60 minutes; initial setting: no less than 6–12 hours; full curing: no less than 24–48 hours; consumption for artificial grass: approximately 0.8–1.2 kg/m²; working temperature for application: from +10°C to +30°C; operating temperature from -40°C to +120°C; density of component A: about 1.5–1.7 g/cm³; density of component B: about 1.1–1.2 g/cm³. Properties: high elasticity, no shrinkage, moisture resistance, resistance to atmospheric effects and temperature fluctuations. The kit includes two components: component A: main paste (polyurethane resin with fillers); component B: liquid hardener (isocyanate) in a separate small bottle.
Laminated particle board. Characteristics. Color range: neutral light gray shade that easily combines with both bright colors and wood decors.; Surface type, texture: embossed / pe (fine grain); Base: E1 emission class chipboard - E0.5; Thickness: at least 16 mm / 18 mm; Sheet format, length: at least 2800; Width: at least 2070 mm; Sheet area: at least 5.03 m²; Density: usually varies from 650 to 750 kg/m³; Laminated on both sides; Grade 1.
