 · Resin Sand Casting. Resin sand casting is a kind of floor molding process, by mixing the resin with quartz sand and solidification agent, to create the very hard and solid mold. The resulted resin sand casting product will have smooth surfaces, accurate dimensions, and less sand residual and casting defects on the surfaces or inside.

 · Make sure to mix resin and hardener as per the label instructions. Stir the mixture slowly with an ice-cream stick for 3 minutes. Scrape the sides of the cup while stirring as to mix the resin and hardener properly. If the mixture is not mixed correctly it might lead to a tacky outcome that just might not cure.

We manufacture Resin Coated Sands, which are processed using high grade silica sand. By pre-coating it with catalyst and phenol-formaldehyde (PF) resin, this sand is prepared. This sand is manufactured in our ultra modern coating plant. Our sand is free flowing, smooth and dry with better resistance to moisture. It is offered in grains form also.

 · A plane-strain unit-cell finite element model was proposed to study the effects of resin/sand interface adhesive and resin cohesive strength on the overall tensile strength of resin sand, as well as the fracture modes. The main micro-scale characteristics of the numerical model were extracted from the micrograph of resin sand specimens by three …

Resital Precoated Sand. HA's Resital Precoated Sand is based on quartz sand, evenly coated with a layer of Corrodur solid resin and the required curing agent. The excellent flow properties and mould filling capabilities of this dry, precoated sand allow even the finest wall thicknesses to be perfectly reproduced.

 · 4. The resin and catalyst have a pungent odor, and good ventilation in the workshop is required; 5. The price of resin is higher. The most widely used resin sand is furan resin self-hardening sand. Furan resin is based on furfuryl alcohol and is named after the unique furan ring in its structure.

Apply with knife or brush. Can be thinned with a small amount of distilled water if required. Mix with different consistencies and ratios of acrylic color/medium to create custom texture. Start by adding very small amounts of color and build up as needed. Overpaint when dry with acrylic color.

The binder is supplied in three parts a phenolic resin in an organic solvent (0.8%), methylene diphenyl diisocyanate (MDI) (0.5%), and a liquid amine catalyst. When mixed with sand, the amine causes a reaction between the resin and the MDI, forming urethane bonds, which rapidly set the mixture. The speed of setting is controlled by the type of ...
