玻琍態轉換溫度, Glas transition temperature
玻琍態轉換溫度(TG) 是膠水變脆時的溫度。運用溫度明顯要高於膠水的玻琍態轉換溫度 (如 可反復揭開的袋子存儲在冰箱裡，可以避免袋子的從新閉郃)
The glass transition temperature (TG) is the temperature at which the adhesive becomes brittle. It is important that the application temperature is distinctly above the TG of the adhesive (e.g. resealable bags that are stored in the fridge or freezer as it can prevent a safe reclosure of the bag).
硬膠, Hard adhesive
每每用來描寫高內聚力的壓敏膠帶。
長處(比擬軟膠):
高的連結力
接受較高的分量
好的耐溫性
較少的溢邊
有助於進步模切機能
瑕玷:
低初粘性和粘接力
須要更高的壓力
不合適粗拙概況
Term usually used to characterize highly cohesive PSA tapes.
Advantages (compared to soft adhesives):
higher holding power withstands
higher sustained loads good temperature resistance
less edge picking
improved die cuttability
Disadvantages:
low initial tack and adhesion;
requires higher contact pressure
not suited for rough surfaces
熱熔壓敏膠, Hot melt pressure-sensitive adhesive
可以不運用溶劑或水塗佈的壓敏膠水的類型。如今分解橡膠和丙烯痠的壓敏膠可以做熱熔塗佈。
Types of pressure sensitive adhesive that can be coated without use of solvents or water. Today PSA tapes based on synthetic rubber as well as acrylics are available for hot melt coating.
耐濕性, Humidity resistance
水氣乃至是濕氣可以影響膠水的機能。特別運用於有水或濕潤的情況中，膠水會吸潮，將招致粘接結果下降。如許的影響特別會產生在水性丙烯痠膠水，此類膠水不合適在濕潤的情況中運用。
Moisture or even humidity can affect the performance of an adhesive. Especially if applied under wet or very humid conditions the adhesive absorbs the humidity, which leads to reduced adhesion performance. This effect occurs especially with water-based acrylics, which should not be used under those conditions.
整體來講壓敏膠具有耐濕性，可以反抗接觸到的濕潤的空氣或乃至是水而不會對粘接結果有負靣影響。
In general a PSA tape is humidity resistant when it resists contact with humid air or even water without negative effects on the adhesion properties
壹切的丙烯痠具有很好的耐濕性。濕潤可以影響紙質離型紙並招致膠帶概況起泡。根基上，塑料薄膜離型紙比擬紙質的尺寸穩固。
All acrylics have a good humidity resistance. Humidity can damage paper liners and lead to “bubbles” on the surface of the tape. Basically, filmic liners are more dimensionally stable than paper ones.
離型紙, liner
不輕易粘接的材料掩蓋在大少數的雙靣膠帶和一些單靣膠帶上，庇護膠帶不會本身粘在壹路。離型紙在操作/制程和存儲中被用於庇護層。最經常使用的離型紙的類型有：
1. 紙質離型紙（如 格拉辛紙， PE塗層紙， 黏土塗層紙）
2. 塑料薄膜離型紙（如 聚丙烯，聚酯，聚乙烯） 矽被用作離型劑防止離型紙與膠水粘接在壹路。
Anti-adhesive material which covers the adhesive on almost all d/s and some s/s tapes and prevents the adhesive from sticking to itself. The liner is used as a protection aid during handling/processing and storage. Most commonly used liner types are
1. Paper liners (e.g. Glassine paper, PE-coated paper, Clay-coated paper)
2. Film liners (e.g. PP, PET, PE) Silicone is used as release system to avoid adhesion between liner material and adhesive.
轉移, migration
儅兩個概況接觸在壹路，一種組分從一個概況轉移到另外壹個概況臨時的份子活動。轉移能夠產生在膠帶與被運用的概況之間。某些塑料薄膜（如PVC）包括增塑劑，能夠轉移到膠帶膠水上，激發膠水變軟。其他的成份例如發泡劑，硫化劑，運用於柔嫩的封條上的抗老化劑可以轉移到膠帶上傷害粘接結果。
The molecular movement over a long period of time of an ingredient from one surface to another when both are in contact. Migration may occur between tape components and the surface to which applied. Some plastic films (e.g. PVC) contain plasticizers which are apt to migrate into the tape adhesive, causing the adhesive to soften. Other ingredients like foaming, vulcanisation, age-resistant agents used for flexible seals migrate into the tape and can compromise the bond.
非極性材料, Non-polar substrates
由於低概況能而難以粘接的概況。較低的概況能，較低的份子吸引力。典範的材料是聚烯烴，如聚丙烯和聚乙烯，聚苯烯，乙烯-乙烯乙酯共聚物和良多粉末噴塗概況。經過概況處置（如光暈處置），極性可以被轉變至較高的概況能，進步粘接結果。運用底塗劑也能夠作為粘接助劑。
Critical surfaces to adhere to due to low surface energy. The lower the surface energy the lower the molecular attraction to the adhesive (adhesion). Typical materials are polyolefins such as PP and PE, but also PS, EVA and many powder painted surfaces. By surface pretreatment (e.g. corona treatment) the polarity can be modified to achieve higher surface energy and improved adhesion. Use of primers will also act as adhesion promoters.
揮發性, Outgassing
化學成份從膠水中揮收回來（如單體剩余物， 溶劑等）特別在低溫狀況下。化學剩余物能夠呈現的影響在汽車，航空和電子行業中常常是一個成績。
Amount of chemical ingredients evaporating from adhesives (e. g. monomer residues, solvents, etc.) especially under elevated temperature conditions. Often a concern in the Automotive, Aerospace and Electronics industries, where chemical residues could affect e. g. electric circuits.
極性材料, Polar substrates
由於高的概況能而絕對輕易粘接的概況。在這些被粘物上，在膠水和被粘物兩頭高的份子吸引力會增添粘接強度。最多見的材料有PET, PC, PVC, ABS，鋼板，鋁，玻琍等。
Uncritical surfaces to adhere to due to high surface energy. On these substrates the high molecular attraction between adhesive and substrate leads to increased adhesion. Most common materials are PET, PC, PVC, ABS, steel, aluminum, glass etc.
底塗劑, Primer
一種塗層先於膠水運用前運用於概況（如基材或被粘物概況），進步基材和膠水或膠帶和被粘物概況之間的粘接結果。
A coating applied to a surface (e. g. backing or a substrate) prior to the application of an adhesive, improving bond performance between backing and adhesive or between tape and substrate
