MAGIK 85-20

(UL CLASSIFIED Water Based Quick Tack Duct Adhesive)

MAGIK 85-20 is a UL Classified, zero VOC, a premium quality water-based adhesive, with high tack and rapid setting. MAGIK 85-20 is based on a very special type of synthetic resin, with very high-performance additives, fine grade mineral fillers, and tackifier. MAGIK 85-20 is non-flammable when wet and fire-resistive when dry.

12 months from date of manufacturing in original unopened containers.

Store product (10oC – 40oC) for maximum storage life. Higher temperatures reduce normal storage life. Lower temperatures may cause increased viscosity of a temporary nature. Rotate stock on a “first in-first out” basis.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging.

Method of Application

MAGIK 85-20 is recommended for bonding of fire rated duct fabric,
low Density duct liner, duct wrap, & fibrous glass insulation to
painted or unpainted steel, galvanized or aluminum surface.
MAGIK 85-20 can also be applied as a contact bond adhesive,
being applied to both surfaces in areas where water entrapment
may be a problem such as polystyrene to metal. MAGIK 85-20 is
ideal for bonding fibrous glass insulation to concrete, block and
other masonry surface in building construction. MAGIK 85-20 can
also be used for ASJ, FSK, PVDC and PVC Jackets.

Conforms To

  • Military Spec. MIL-A-3316C, Class 2, Grade A.
  • LEED IEQ 4.1, Low Emitting Materials, Adhesive
  • & Sealants (VOC <50 g/ltr).
  • SCAQMD Rule 1168 & 40 CFR 59..
  • NFPA 90A and 90B 25/50.
  • ASTM C916 Type II.
  • DCL Approved.
  • Free of asbestos, lead and mercury compounds.
Surface Preparation:
  •  The surface should be structurally sound, clean, dry, leveled and free from dust, curing compounds, grease and other loose debris. Keep container closed when not in use.
Application Procedure:

For wet bond application apply MAGIK 85-20 uniformly on the metal surface at 8-14 m2/liter. While wet, apply pressure to assure intimate bond.

For contact bond application apply MAGIK 85-20 uniformly on the metal surface at8-12 m2/liter. Coat the insulation surface at 3-5 m2/liter. Allow the adhesive to tack fully and allow the moisture to evaporate for 20-45 minutes, depending on the local environment. Position the two mating surface together and apply pressure to assure intimate bond.
