Coatings
MinVasive Components has the right coating for nearly any application, from polyurethane-SB with a self-bonding overcoat of thermoplastic adhesive, to polyimide, where toughness, abrasion resistance and resistance to solvents are required. Polyester is also available in several iterations.
POLYURETHANE-SB
Self-Bonding
Overcoat
NEMA MW-3
NEMA Class
105
Class
105-Type SUB-SUB2 |
Polyurethane
with a self-bonding overcoat of thermoplastic adhesive. Coils
hold shape without tape or varnish. Bonding may be accomplished
by resistance heating, oven heating, or activation during
winding with alcohol or other suitable solvent. Applications:
High quality voice-coils, small yoke coils, complicated coils
which must be self-supporting and encapsulated coils wound
without bobbins. |
POLYURETHANE-N
Polyamide
Overcoat
NEMA MW-28
NEMA Class
130
JW-1177/9
Class
130-Type SUN-SUN2 |
Polyurethane
base with polyamide overcoat for improved winding and added
protection from encapsulation materials. Used in applications
requiring solderable magnet wire with dependable performance at
130°C with overload protection. Not to be used where high “Q”
values are required. Applications: Armatures for
portable tools and appliances, random wound coils with high turn
pressures, solenoids, torroidal coils. Avoid use for IF and RF
coils or for transformer oil and hermetic motors. |
FORMVAR
NEMA-MW-15
NEMA Class 105
JW-1177/4
Class
105-Type T-T2 |
Formvar
where toughness, abrasion resistance, and resistance to solvents
are required. Applications: Random wound stators and
armatures, DC motor and generator windings, and transformers. |
POLYESTER-N
Polyamide
Overcoat
NEMA MW-24
NEMA Class
155
JW-1177/11
Class
155-Type LN-LN2 |
Insulation
film of modified polyester base with an overcoat of polyamide
results in good windability, flexibility and resistance to
heat/solvent shock. Moisture containing or generating
insulations are not compatible with polyamide overcoat.
Preheating prior to varnishing should be gradual. Avoid
insulating materials containing chlorine. Applications:
Motor and generator windings. |
SOLDERABLE POLYESTER
NEMA MW-26
NEMA Class
155
JW-1177/10
Class
155-Type L-L3 |
Solderable
Polyester magnet wire, a modified polyester resin solderable
without prior stripping at 850 to 875°F. Good windability,
flexibility and resistance to heat/solvent shock. Moisture
containing or generating insulations are not compatible with
solderable polyester. Preheating prior to varnishing should be
gradual. Avoid insulating materials containing chlorine.
Furnished with or without a nylon overcoat. Applications:
Motor and generator windings, solenoids, relays. |
POLYESTER-AI
Polyamide-imide
Overcoat
NEMA MW-35
NEMA Class
200
JW-1177/14
Class
200-Type K-K2 |
Overcoat of
polyamide-imide applied over a base coating of polyester for
improved windability, more resistance to heat/solvent shock and
thermoplastic flow, and less potential to solvent crazing.
Preheating prior to varnishing should be gradual. Insulating
materials containing chlorine should not be part of an enclosed
or sealed system. Applications: Motor windings,
solenoids, and numerous other Class-200 applications. |
POLYIMIDE
NEMA MW-16
NEMA Class
230
JW-1177/15
Class
220-Type M-M2 |
Replaces
most film-insulated magnet wires in electrical apparatus
operating up to 230°C, where increased component output is
required from miniaturized components or without increasing
size. Compatible with most varnishes and encapsulating
compounds. Ideal where extremely high cut-through resistance is
required. Applications: Aerospace systems. AC and DC
motors/generators, hermetically sealed motors/relays, dry-type
transformers, and all types of encapsulated windings. |
