Collision repair materials碰撞维修材料

In car body collision accidents, it will generally lead to structural deformation, steel plate cracking, solder joint desoldering, etc., and sometimes local damage to other assembly parts such as the integrated electric drive assembly and chassis. When performing vehicle collision repairs, adhesives, sealants, anti-loosening agents, surface protection materials, anti-corrosion materials, and chemical materials may be used. Please strictly follow the purpose, scope of use, and usage specifications in the product manual. During the car body repair process, repair materials with the same functions should be selected according to the functional requirements of the parts and materials. The following table lists the repair materials that may be used in the car body repair process, for reference only during the car body repair process.在车身碰撞事故中，一般会导致结构变形、钢板开裂、焊点脱焊等现象，有时还会造成集成电力驱动总成、底盘等其他装配零件的局部损坏。进行车身碰撞维修时，可能会用到粘结剂、密封剂、防松剂、表面防护材料、防腐材料、化学材料，请严格按照产品说明书中的用途、使用范围以及使用规范进行操作。在车身维修过程中，要根据零件材料的功能要求，选用功能相同的维修材料，下表列出了在汽车车身维修过程中可能使用到的维修材料，仅供在车身维修过程中参考。

Room temperature curing adhesive for sealing car body welds.室温固化型粘结剂，用于车身焊缝处的密封。

Room temperature curing adhesive for fine sealing at the folds of doors, hoods and luggage compartments (trunk boxes).室温固化型粘结剂，用于车门、发动机罩和行李箱(后背箱)折边处的细密封。

Anti-stone chip primer抗石击底涂

Rubber and resin橡胶和树脂

Room-temperature curing anti-collision glue for chassis protection forms a permanent anti-aging, elastic and corrosion-resistant protective coating on the car bottom and wheel covers, with no cracks at low temperatures.室温固化型底盘防护用防撞胶，在车底、轮罩处形成一层永久的抗老化的弹性耐腐蚀保护涂层，低温下无裂纹。

This type of product can replace PVC coating and has excellent anti-rust, sound insulation, anti-stone chip, anti-oxidation, protective coating and other functions.此类产品可以取代PVC涂层，具有优良的防锈、隔音、防石击、抗氧化、保护涂层等功能。

Windshield glue风窗玻璃胶

One-component polyurethane单组份聚氨酯

Room temperature curing polyurethane adhesive, used for direct bonding and sealing of automobile window glass.室温固化聚氨酯胶粘剂，用于汽车窗玻璃的直接粘结、密封。

The glue has good bonding properties, reacts with moisture in the air, and solidifies to form excellent properties such as high strength, aging resistance, vibration fatigue resistance, low temperature resistance, and no corrosion.该胶具有良好的粘结性能，与空气中的水分发生反应，固化形成具有高强度、耐老化、耐震动疲惫、耐低温、无腐蚀等优异性能。

Primer底涂剂

Before applying windshield glue, you need to apply a primer on the car body and glass to make the windshield glass and car body bond more firmly.在涂敷风窗玻璃胶前需在车身及玻璃上涂布一种底胶，使风窗玻璃与车身粘结的更牢固。

cleaning agent清洗剂

Used to clean all surfaces in contact with primers and adhesives.用于清洁所有与底层涂料和粘接剂相接触的表面。

pressure sensitive tape压敏性胶带

acrylic tape丙烯酸胶带

Used for bonding anti-scratch strips, nameplates, cover panels, cover panels, door edge protection, various decorative strips on the body, etc.用于防擦条、铭牌、护板、挡泥板、门边保护、车身各种装饰条等的粘结。

The tape should have excellent weather resistance and durability.此胶带要有卓越耐候性和耐久性。

heat sensitive tape热敏性胶带

acrylic tape丙烯酸胶带

Mainly used in rubber sealing strip systems on automobiles.主要用于汽车上橡胶类密封条系统。

This type of tape must have strong bonding force and strong sealing performance to avoid gaps and corrosion problems caused by weak bonding.此类胶带要有很强的结合力和较强的密封性能，避免粘结不牢而出现间隙和腐蚀问题。

Base glue for tape胶带用底胶

Depending on the material of the bonding surface, different primers are used. The bonding surface must be clean. After it is completely dry, use a brush to apply the primer evenly on the surface to be bonded. After drying, apply the tape to make the tape have strong adhesion.根据粘结表面的材质，选用不同的底胶。粘结表面须清洁干净，待彻底干燥后用刷子将底胶均匀涂在被粘表面，待干燥后粘贴胶带使胶带有很强的粘结性。
