Macropoxy K267

Technical Information

Sherwin-Williams Macropoxy 1210 (formerly known as K267) is a high solids 2-pack epoxy, pigmented with micaceous iron oxide.

Where To Use

As an intermediate coat in conjunction with Macropoxy high performance primers. Also recommended as primer for painting galvanised steel.

Application Process

Airless Spray Nozzle Size: 0.46mm (18 thou) Fan Angle: 80° Operating Pressure: 155kg/cm² (2200 psi) The airless spray details given above are intended as a guide only. Details such as fl uid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen. However, the operating pressure should be the lowest possible consistent with satisfactory atomisation.

As conditions will vary from job to job, it is the applicators’ responsibility to ensure that the equipment in use has been set up to give the best results. If in doubt Sherwin-Williams should be consulted.

Conventional Spray Nozzle Size : 1.27mm (50 thou) Atomising Pressure: 3.5kg/cm² (50 psi) Fluid Pressure : 0.7kg/cm² (10 psi)

The details of atomising pressure, fluid pressure and nozzle size are given as a guide. It may be found that slight variations of pressure will provide optimum atomisation in some circumstances according to the set up in use.

Atomising air pressure depends on the air cap in use and the fl uid pressure depends on the length of line and direction of feed i.e. horizontal or vertical. For application by conventional spray, it may be necessary to thin the paint by the addition of up to 10% Cleanser/Thinner No. 5. Where thinning has been carried out the wet film thickness must be adjusted accordingly.

Brush

The material is suitable for brush application.

Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray applied coat.

Roller

The material is suitable for roller application. Application of more than one coat may be necessary to give equivalent dry fi lm thickness to a single spray applied coat.
