Usage Information

Method of Application

permits the use of high-speed production methods. The

powder can be readily applied by spraying techniques as

well as through the use of fluid bed dipping of preheated

parts. Automated and manual types of application equipment

are both available. Equipment manufacturers’ names can be

suggested upon request.

Curing

The cure of resin 260 to a thermoset condition is a time/

temperature relationship. The retained heat in application

units having high heat capacity is sufficient in many cases

to effect a cure of the resin without the need for post-curing

facilities. For example, if an application surface can retain a

temperature of 204°C (400°F) for 45 seconds after coating,

it will be fully cured. Small articles, or those with a large

surface-to-mass ratio, lose heat rapidly and

may require a higher preheat temperature and/or additional

oven-curing.

The figures below represent nominal guidelines for

obtaining the resin’s adhesion, impact and chemical

resistance characteristics.

Time does not include that required to reach the cure

the coated substrate to reach listed temperatures.

Preheat Temperature Range

Prior to applying resin 260, the part must be preheated to

a temperature ranging from 150°C (302°F) to 260°C

(500° F). The optimum preheat temperature depends upon

the size, heat capacity and configuration of the object to

be coated, as well as the method of application. The ideal

coating temperature will vary for each application and is

best determined by experimentation.

Storage

Laboratory evaluation indicates that the usable shelf life

of this product is twenty four (24) months from the date of

manufacture when stored at temperatures not exceeding

27°C (80°F), provided the material is stored in its original

container. For 260 8G, the usable shelf life is twelve (12)

months under the same conditions. Care should be taken

when removing resin from the original shipping container

to prevent inclusion of foreign material. After resin removal,

the bag should be retied immediately. This will help to avoid

agglomeration caused by excess moisture. For best results,

store in a cool, dry place.

UL Recognition

Scotchcast electrical resin 260 has UL 1446 system approval

as major insulation for use in motor, transformer, and coil

constructions. The product is listed under File Number

E163090, System Designation 3M120-1, 3M130-1,

3M155-1,and 3M180-1. These systems are rated class E, B,

F and H respectively. Resin 260 is also recognized in UL file

#E35075, Guide QMFZ2.

Users interested in applying these insulation systems to

their design are invited to contact 3M for an approval letter

to obtain access to the UL file for further information.

Underwriters Laboratories (UL) recognized products

have been evaluated for use as components of end product

equipment that is listed or classified by UL.

To achieve Underwriters Laboratories recognition,

component construction must meet UL specifications and

conditions of acceptability for proper and safe use of the

component or product.
