Mayen’s New Generation epoxy resin worktop adopts the newly developed epoxy resin system, the new production process and the fully automated production process technology. This integrated core epoxy resin worktop is patented, processed by multi-process and high temperature compounding. This matte finish surface epoxy resin worktop is processed by more than 40 fully automated polishing equipment, so it has uniform thickness.

 

Mayen’s New Generation epoxy resin worktop retains the chemical stability, heat resistance and mechanical properties of the traditional epoxy resin worktop. It is of superior corrosion resistance, excellent high temperature resistance, durable reducibility, environmental safety.

 

Mayen’s New Generation epoxy resin worktop strengthens the surface hardness of the product and enhances the mechanical strength and increases the scratch resistance. It improves the production capacity perfectly and increases the molding area of the product. The single piece can be molded into 3000mmx1600mm, which can meet the design and installation of super large laboratory worktop for the projects.

ADVANTAGES OF MAYEN EPOXY RESIN WORKTOPS

 

DURABILITY

MAYEN epoxy resin worktops are monolithic and non-porous; they do not delaminate or swell. They are easy to install on site.

 

APPEARANCE

MAYEN epoxy resin worktops have a smooth and matte surface that is easy to clean and maintain.

 

CHEMICAL RESISTANCE

MAYEN epoxy resin worktops are highly resistant to the corrosive effects of most chemicals and organic solvents and compounds.

 

HEAT RESISTANCE

MAYEN epoxy resin worktops will not blister or crack when exposed to extreme temperatures in the laboratory.

 

SAFETY

MAYEN epoxy resin worktops are enhanced by a natural, asbestos-free additive, providing fire resistance and insulation properties in a user-safe environment.

 

INDOOR AIR QUALITY

MAYEN epoxy resin worktops are low-emission certified.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

CHEMICAL RESISTANT PROPERTIES TESTING

 

Method A

Used for Volatile Chemicals (organic solvent):

A cotton ball, saturated with the test chemical (reagent), is placed in a 1-ounce test tube with a reservoir of liquid above the ball. The container is inverted on the test material at a standard temperature of 23 plus or minus 2 (73°plus or minus 4).

 

Method B

Used for Non-Volatile Chemicals:

5 drops (1/4cc) of the test chemical are placed on the test material surface. The chemical is covered with a watch glass (d=125px) at a standard temperature of 23°plus or minus 2 (73°plus or minus 4).

 

For both the above methods (A and B), leave the reagents on the panel for a period of: 1 hour for exposed vertical surfaces and semi-exposed surfaces, 24 hours for exposed horizontal surfaces such as countertops. After exposure, exposed areas are washed with water, then a detergent solution, finally with naphtha, then rinsed with distilled water and dried with a cloth.

Test Evaluation

The effect on the surface of the specimen is inspected visually and express in accordance with the following rating scale:

1

No effect

: No detectable change   in the material surface.

2

Excellent

: Slight   detectable change in colour or gloss, but no change to the function or life   of the work surface material.

3

Good

: Clearly discernible change in colour or gloss, but no   significant impairment of surface life or function.

4

Fair

: Objectionable   change in appearance due to surface discoloration or etch, possibly resulting   in deterioration of function over an extended period.

5

Failure

: Pitting,   cratering or erosion of work surface material; obvious and significant deterioration.

MAINTENANCE AND REPAIR

MAYEN epoxy resin worktops will not stain and are resistant to most abrasive chemicals. Periodic cleaning with a 70% ethyl alcohol solution is recommended (other waxes or coatings should not be applied). MAYEN epoxy resin worktops can suffer damage however through abuse or neglect. Scratches and marks can usually be repared on site using the following materials and procedure:

 

Material required:

Oil (mineral or light machine oil)

Silicone Carbide Sandpaper (grits 80, 120 and 220)

3M Scotch Brite (or equivalent)

Clean cloths

Depending on field conditions, either hand-tools or power-tools may be used to repair scratches.

 

Procedure:

1.     Apply oil to the area to be repaired, then begin sanding with 80 grit sandpaper in the same direction as the scratch using a moderate to light touch until scratch disappears. The lighter the pressure, the less material is removed, and the better the repair will look.

2.     The final sanding should be done using 220 grit paper and oil. Again, work in the same direction as the scratch using a light touch. Use plenty of oil to remove sanding marks from the work surface. Buff the sanded area with oil and 3M Scotch Brite until you are satisfied with the result. Buff further with clear rags and the repair is complete.
