Kemko® 322 Ultra Low Viscosity IR (ULV)
Injection Resin – Ultra-Low Viscosity, Cold Weather, Epoxy-Acrylic for Presure Injection
Description
KEMKO® 322 Ultra Low Viscosity IR (ULV) is a two-component, low viscosity, structural epoxy hybrid adhesive resin specifically designed for cold weather 35ºF (1.7ºC) pressure injection grouting using KIP™(KEMKO® Injection Process) System automatic meter, mix and dispensing application equipment. Primary uses include the structural repair of cracks and delaminations in concrete as low as 2 mils (0.05 mm), masonry, stone, and wood; filling of voids in porous and honeycombed concrete and grout; adhesive bonding of steel plates (external reinforcement); and anchoring bolts, dowels, and rebar into concrete, masonry, or stone. Use as the adhesive for CFRP (carbon fiber-reinforced polymer) applications. Applications requiring material thickness in excess of 1/4 inch (6.35 mm) may be facilitated by pre-placing aggregate in the void. It is also an excellent primer or Healer/Sealer horizontal concrete substrate flood coat placed at 80 to 125 sq. ft. (7.48 to 11.15 sq. m.) per gallon (3.79 l.). For skid-resistance broadcast a US Sieve Size 30 – 50 mesh aggregate, uniformed in size, washed, dried, and bagged. KEMKO® 322 bonds to damp, wet, and underwater substrates. It contains no VOC’s (volatile organic compounds).
- Meets - ASTM C881 and AASHTO M235, Type I, II, & IV, Grade 1, Class A, Class B, & Class C (modified, it is an epoxy/acrylic)

Features
The physical properties of the product allow its use in applications requiring resistance to creep and stress relaxation, maintenance of mechanical properties at high ambient temperatures, high load bearing strength, and excellent adhesion under adverse application conditions, e.g., cold temperature substrate, wet concrete. KEMKO® 322 cures to a tough, resilient polymer and has excellent load transfer capability. Exceptional substrate wetting ensures penetration and filling of fine fissures and tributary cracks as narrow as 2 mils (0.051 mm) width. It has a convenient 2:1 (by vol.) mixing ratio and employs special colorants for contrasting component color.
