Primer for concrete pouring/Highly durable floor finishing agent TM-7416

A civil engineering primer that can be applied to concrete pouring and infrastructure repair.
It can also be applied as a floor finishing agent by taking advantage of the gloss and durability of the dried paint film.

Characteristics

  • In addition to painting and adhering to normal concrete dry surfaces, it can also be applied as a primer to wet concrete surfaces for new concrete pouring.
  • It has strong adhesive properties as a primer for pouring and pouring even on oil-contaminated concrete surfaces (oil-wet surfaces).
  • It exhibits excellent adhesion even to different types of resin coatings.
  • The coating surface has good gloss and has excellent chemical and water-based.
  • A resin varnish for floor painting that is stain-resistant and has friction properties that prevent it from slipping even after water repellent.
  • A paint varnish that can be easily applied to concrete using a wool roller or brush.
  • Since it is a water-soluble resin, it can be cleaned with water.

Application example

  • Adhesion of new and old concrete mortar joints
  • Renovation floor repair adhesive primer (gas stations, factories, kitchens, warehouses, stores, etc.)
  • Various renovations and repairs (tunnel walls, dams, roads, bridges, waterways, etc.)

Applicable base

concrete bridge
Concrete, mortar, painted floor, steel plate, tile, FRP, etc.

how to use

Diluent: water, IPA, ethanol
Combination example: TM-7416/diluent/CAT-1955=100/40/20
Application method: Woo roller, brush, etc.
Application amount: Wet 150-200g/㎥
Drying: room temperature drying
Curing: Dry at room temperature for 3 to 5 hours until tack-free, dry at room temperature for 1 week until completely cured
Pot life: 6-8 hours

Basic composition

  1. First, add the diluent (usually water) to the base material TM-7416, stir and mix, then add the curing agent and mix well.
  2. If the applied surface is extremely wet, remove the water adhering to the surface with a rag, etc., and use a mixture of water/alcohol (IPA, etc.) as the diluent mentioned above.
  3. If you need to speed up drying due to low winter temperatures, use a mixture of water/alcohol (IPA, etc.) as the diluent above.

Examples of diluents

When applying to wet surfaces: Water/IPA = 50/10
To improve dryness: water/IPA=55/5
